ROTARY STEAM-ENGINE.

Speeicatlon of Letters Patent. Patented June 1 8, 1918.I

Application illed Hatch 11, '1916. Serial No. 83,533.

' is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make, construct, and use the same, reference being had to the accompanying drawings', and to numerals of reference' marked thereon, forming a part of this specification.

This invention relates to rotary steam engines, and consists in mechanisms whereby the act of starting, stopping, and reversing the engine is performed by a simple movement of the throttle, with lightning-like rapidity and perfect control at any speed, without shock or jar; as the inertia of the mass of steam is cushioned against the pressure at the boiler.

The objects of my invention are to increase the simplicity of the construction and operation of the engine, by decreasing the number of parts of which the usual engine is composed; by lessening or avoiding the necessity for adjustment of the various parts, and by increasing the convenience in manipulation of the engine. -To this end, I have made many changes in this engine from similar engines described in previous patents; all with the object of increased eiliciency.

Enumerating the diierent features of my invention, I would say that firstly, I construct the central rotating member or hollow shaft with two pistons attached, and pro-A viding said pistons each with an increased piston area. The hollow shaft is provided with eduction ports communicating with the engine casing to permit the spent steam to be exhausted therethrough, and out through the base into the atmosphere. Secondly, my invention" consists in the novel construction of the balanced sliding steam valve, with three ports accurately spaced, which is movable end-wise or horizontally Within the central rotating member or shaft to which the two pistons are attached, and over a stationary steam sleeve, which is provided`with a plurality of ports registering witha steam chamber and the ports in said sliding valve, so that a forward movement mosphere.

, constructions, ments of parts, as hereinafter set forth.

of the throttle, which is secured to the balanced-steam valve, moves said valves and brings a port in the valve .in line with a port in one of the pistons through which the steam travels to the steam chamber. Continued movement of the engine cuts off the supply of steam and the piston continues to move on expansion until the yrelated port in the other piston is in line with another port in the valve. Atthis point, the pistons trade functions and the spent steam is exhausted through the reverse port in the idle piston to the hollow shaft, and thence through the eduction-ports in the shaft to the engine casing out into the at- A backward movement of the throttle brings the valve ports in line with the reverse ports in the pistons, performing the same operations for the reverse as for the forward movement.

The invention comprises certain special combinations and arrange- In the drawings, in which like numerals of reference indicate corresponding parts;`

and the onethe pistons secured thereon,

located" in the way stationary steam valve ner, these two constituting one working part,

and the three conical rolhng cylinder heads 3, constitutin the r three parts, the rollin cy der heads being each provided wit pockets or cavities to allow the pistons to pass through. Each member revolves upon its own center oil revolution byv gearing to a inion secured on the central shaft. All o the aforesaid four parts revolve in the same plane and are entirely gyroscopic in motion, thus insuring against noise and vibration.

The engine casing consists or a housing 4, provided with a circumferential annular opposite pistons 2, adapted to travel therein. As previously stated, the pistons 2 are properly secured by means of a key or otherwise to the central hollow rotating member or shaft 1, which shaft is supported in suitable bearings 6 and 6 formed on the covers 7 and 8 of the engine casing, so that travel of the pistons 2 will cause rotation of said shaft 1. -Arranged in the corners of an' equilateral triangle at'points across the anv fengage with a gear wheel 10, secu nular chamber 5 and pathway of the pistons 2, are the three conical rolling cylinder heads 3, each rolling cylinder head being provided with a gear-wheel 9, desi ed to to the rotating member or shaft 1, whereby said rolling cylinder heads 3 are caused to turn to present the'pockets or cavities 11 to allow the pistons to pass through.

At equidistantpoints through the walls of the covers 7 and 8 of the engine casing, are arranged tubular` extensions 12, each provided with a suitable cap or cover 13, said tubular extensions 12 having secured therein suitable ball-bearings 14 in which the ends 15 ofthe rolling cylinder heads 3 are secured.

The bearings 6 and 6 of the covers 7 and 8 are also provided with suitable caps or covers 16 and 17, said bearings having secured therein suitable bali bearings 18, in which the ends of the central rotating member or shaft 1 revolve.' The cover 17 also acts as a yvalve guide, to which the throttle interet 19 is pivoted, as clearly indicated in Figs. 1 and 2 of the drawin s, one end of the throttle being convenient y secured to one end of the balanced steam valve 20, as in the reversing type of engine, in any desired or convenient manner. The stationary steam sleeve 21 is conveniently secured to the end a hollow, tubular member provided at its open end with preferably an inte l collar 23, by means of which, it, toget er with the union 22, is secured to the end of the cover 17 and near. its closed end, said startionary steam sleeve is provided with a plu-v rality of ports 24 registering with the steam chamber 25 of the balanced-sliding steam valve 20. The balanced-steam valve 20 is provided with a central bore 26, designed to receive the stationary steam sleeve 21, and with which said steam valve 20 has sliding engagement.

The closed end of the sliding steam valve 20 is provided with a tubular extension 27, designed to have sliding engagement with the reduced portion of the hollow shaft 1 with which the steam valve 20 has sliding engagement.

The sliding steam valve 2O is provided with three ports 28, accurately spaced, commimicating with the steam chamber 25, and the hollow shaft 1 is also provided with ports 29 registering with ports 30 formed in the piston 2, so that a forward movement of the throttle, which is secured to the balanced vsteam valve, brings a port in the valve in line 4with the port in one of thepistons, through whichthe steam travels to the steam chamber 5. 5 y

In the reversing type of engine, as illustrated in Fig. 3 of the drawings, a pair of reverse ports 31 are also employed in the piston, and indicated in dotted lines, through which the spent steam is exhausted through similar ports 32 in the hollow shaft, also said valve being provided with a central longitudinal bore 36, and which is rigidly secured to the end of the cover 17, in any desired or convenient manner, the closed end of which is also provided with a tubular extension 37, designed to have engagement with the reduced portion of the hollow shaft 1, in a similar manner as the tubular extension 27 of the sliding valve 20 is illustrated in Fig. 2 of the drawings. The one-way valve is also provided with three ports 38, accurately spaced, communicating with ports 39 of the hollow shaft 1, see F ig. 8 of the drawings, which ports 39 register with ports 40 formed in the piston 2, through vhgi the steam travels to the steam cham- The pistons employed in the non-reversing type *of engine are only provided with a single set of ports 40, as distinguished from the pistons employed in the reversing type of engine, which are provided with two sets of orts, namely, ports 30 and 31.
